IMPROVEMENT IN WOOL-WASHING MACHINES.

Specification forming part of Letters Patent No. 203,995, dated May21,1878; application filed April 11, 1878.

To all whom it may concern:

Be it known that I, WILLIAM H. BRADLEY, of Allegheny city, in the countyof Allegheny and State of Pennsylvania, have invented a new and usefulImprovement in Wool- Scouring Machines, which improvement is fully setforth in the following specification, reference being had to thedrawings, in which Figure 1 is a sectional side view, and Fig. 2 is afront view in section.

The object of my invention is to secure a steady and even feed of thewool to the scouring-rolls, thereby causing a more thorough cleansing,and also preventing the strain produced by large lumps of wool enteringthe rolls, which isfrequently the case when the wool is fed by forks orby hand, and results in imperfect cleansing.

In the-drawings, A and B are the scouring or squeezing rolls, havingmotion in the direction of the arrows, and situated at one end of a vatcontaining the scouring or cleansing liquor covering the lowerroll, andextending on an incline into the vat, and securely fastened thereto isthe supporting-plate O, the upper and lower ends of which are planesurfaces. The center is recessed for the play of the connecting-bars Eand F, which rest and move upon the bearings D D, and on the top of theconnecting-bars are placed the feeding slide-bars.c e e and f f f, whichare fastened to E and F, respectively, by rivets 0r screws. Theseslide-bars e and f are placed alternately side by side, covering thewhole surface of the supporting-plate O, and on their top surface theyare provided with the feeding teeth or claws a a a a, which are rivetedor fastened in any suitable manner. On each side of supporting-plate theguards GGar'eplaced. They also act as guides to the connecting-bars Eand F, keeping them in place.

Over the top of the rolls is the shaft H, bearing a series of foureccentrics-two on each side. Of these, J J are arranged to make theirfull stroke together, and are joined, by the curved arms I) b, to theconnectingbar E by the joints 0 0, while K K, having their full strokeset directly opposite to J J are similarly attached, by d d, to F at gg. Hence it follows that motion being applied to the shaft H, in anyconvenient manner, the stroke of the eccentrics is carried to theconnecting-bars E and F, and will, through them, cause the slide-bars eand f to have an alternate upward and downward movement, and thefeeding-teeth a a a a to advance and recede, passing and repassing oneanother.

Thewool in the cleansing-liquor being up to the surface of the underroll, A, which carries it through.

The feed-teeth a are more fully shown in the enlarged drawing, Fig. 3.This formation of the tooth admits of its ready passage nnder the woolwhen returning downward to the vat, and the sharp prongs assist intearing the same apart when advancing upward.

Any number of slide bars and teeth may be used, so that they areproportionate to the size of the machine. I

The advantages of this mode of feeding are that the wool is mostthoroughly cleansed, the breaking up of the lumps allowing thecleansing-liquor to act'upon it, and the complete extraction of the samewhile passing through the rolls. The wool is also in better shape forfuture processes, owing to the action of the machine, and is almost drywhen discharged.

Having thus described my invention, what I claim, and desire to secureby Letters Patent is Iii combination with the squeezing-rolls of awoolscouring machine, the mechanism for feeding the same, provided bythe plate 0, set at an incline, and bearing the series of sliding bars0' and f, having an alternate forward and backward movement from thecocentrics J and K, and armed with the teeth a a a a, the said bars 6and f being secured to their respective connecting-bars E and F, wherebythe wool is evenly advanced and fed to the rolls A B.

WILLIAM H. BRADLEY.
